Well. I've decided to upgrade my Justy's carb, as I am constantly angry with the stock performance. I was thinking an early Civic's carb. Maybe off a 1300cc..? Anyone ever do a cool carb swap on their Justy!? Would love to hear how it turned out, and any suggestions or a reliable carb? Thanks -Terry

I have always entertained the thought of putting a weber carb on a Justy to beef up performance. I just don't know, everytime I look at all those vaccuum lines I decide to leave it all stock. Of course my car runs great. If I had to switch, weber is the way to go.

All the vaccum lines was eliminated, and now this carb has only 4 or 5 lines. I did this swap about 2 years ago, and my Justy runs very well. I had a lot of troubles with the original carb, specialy for be ELECTRO-CARB, this older carb its more simple, and you can buy a kit for fixit for only "3000 colones", (like $6). So you can try a Toyota or Nissan, fron the earlys 80´s in your Justy, the only thing you have to do its a new and costum base. Good Luck.

I just did a carb swap on my Justy and good god damn, there must be 20 hoses on & around that thing. I have read the factory shop manual extensively about that computer controlled carb system and as annoying as that carb is, it does do a very good job of not letting any gas vapor expire into the atmosphere. It's a very 'green' car.

I know when I went through the emissions testing. I passed easily, in fact the needle didn't even move. I have never seen that before. The emissions test is a real money making scam because it judges pollution to air mixtures and doesn't take into account the engine size. The worst justy ever wouldn't pollute as much as a new suv. Although except for some complaints I have gotten about riding in the backseat, I have always thought of my justy as an suv. That's mainly because my father once opened the hatchback and commented,"Just like an suv". He got a kick out of driving it and he was 6'3" tall.

Wow, I don't know how a man of 6'3" could be so happy in a Justy. I'm 6'0" and a proud Justy owner but I'll admit that one of the Justys biggest faults is the lack of legroom.

He is the reason I own a Justy. He always owned Cadillacs but they started making cars that were pretty much junk, so he just used a truck to pull his trailer at that point. He started buying import cars to drive around. Long story but he needed a cheap car all of a sudden and low and behold it was a Justy. The cutest little car imaginable. You've seen the cartoon where the big guy gets out of the small car, that was him. It was his last car and I ended up with it. He didn't drive it much, but he never complained. But since you mentioned it, he must of been cramped a little bit. He still liked it though.

I replaced the stock Hitachi with another stock Hitachi. Mine was OK and didn't really need replacing but I have a friend in need. His car won't start and I have checked everything. After having it looked at by a mechanic, we believe his carb took a dump. I have spare carbs but wanted to test one before giving him a possibly bad replacement. So, I replaced my car's carb with a spare, it worked and now I am going to give him my old one. In fact, I'll be heading over to his place to do just that in about 7 hours.

I have swapped the stock Hitachi for a Keihin.I think it came from an old Civic(never seen the car,only carb and 4cyl manifold).I'm running it for some 6 months now.Nice power,acceptable consumption,relatively easy mounting.It's not eaven tuned yet.Just bolt on and drive.Still using the stock air filter.Only thing i had to do is to widen 2 of the 4 mounting holes,as the keihin has slightly different pattern.

Looks pretty good. What's with the extra fuel filter? I like that rocker/valve cover with only one PCV outlet. I'd be pretty interested in getting one of those. I have a box of about 8 or 9 rocker covers but they are all Federal spec with 2 PCV's.

Extra fuel filter is the layzyman's way of securing clean juice.Why go under the car for just a filter?It's going soon as I'm in the middle of a major bodywork repair. As for the rocker cover,no idea why is that way.All the strange things i've found about that particular car ... It had a restrictor plate under the carb to keep it on the 50hp.Oh,and the Hitachi carb was quite a mistery.Looks different from what i've seen on the forum.

Regarding the fuel filter under the car--isn't it between the gas tank and the fuel pump? The fuel filter's main job should be to keep junk out of the fuel pump itself, not just out of the carb. I'd say that the one in the engine bay is false security, if you don't have one protecting the pump too.
Also, I'd urge everyone with a carbed vehicle to keep a spare fuel filter in the vehicle along with the tools needed to change it out. Beats getting stuck somewhere. Has saved my butt several times, twice on road trips.

Also, I'd urge everyone with a carbed vehicle to keep a spare fuel filter in the vehicle along with the tools needed to change it out. Beats getting stuck somewhere. Has saved my butt several times, twice on road trips. Tom, regarding the fuel filter's location and function, yes you're right, on an EFI Justy it is under the car between the fuel tank and the edge of the door, on a carby Justy it is mounted to the flipside of a skid plate along with the fuel pump in the same location. I'm not sure what to think about the filter guarding the pump theory though. My Mustang had a mechanical pump driven off of the auxiliary shaft and then the filter inline by the carb. That was stock design and never had a problem with it. *shrugs* Dunno. Regarding your advice to always carry a spare and the tools needed to replace it, I would have to disagree. I have owned two Justys & worked on numerous others and performed fuel filter replacements on all of them. They are always well beyond recommended service life and twice I believe to be dealer installed from when the vehicles were still under warranty! Couple the Justy's amazing ability to continue running on a bad filter with the tools you would need to actually perform this procedure in the field and I think I could make an argument against it. You can do it however you like but when I change a Justy filter I have the following tools: A) 2 pair very small locking pliers (AKA vise-grips) B) 10mm socket & ratchet C) 1 pair regular pliers D) clean rag I use the small locking pliers to pinch the fuel lines before removing the filter. You are not swift handed enough to undo the filter and plug the hose without spilling fuel everywhere! therefor it is wise to pre-pinch the lines as mentioned above. The filter will be difficult to get off of said fuel lines and the new one will be equally stubborn going on and this is why I use a clean, dry rag to help grip the hoses. The regular pliers are for the hose clamps and the wrench & socket to remove the various fasteners holding these bits to the vehicle. You could probably do this with the vehicle flat on the ground but I always raise the vehicle to aid in accessing this son-of-a-pregnant dog. As I don't believe in working under a vehicle that is not supported by stands, I would not personally do this on-the-fly because I don't carry flippin' jackstands in my car when I go to buy eggs. If I could advise anyone to carry something extra in their car it would be a litre of bottled water (stored easily next to the overflow tank) because the Justy's cooling system although adequate, doesn't tolerate running low. Just my own experience guys P.S. a special thanks to SubieJim who two years ago when I was new to the Justy scene, helped me locate the fuel filter when I could not locate it myself and I refused to buy a Chiltons guide to tell me as they are money wasted. Haynes never made a guide for the Justy and I now own several Fuji factory books instead.

Good reply, Seattle, But I stand by my experiences of not being stranded several times, due to preparedness. I hate being stuck due to dumb stuff I could have prepared for. I'm a big believer in Murphy's Law; and having been career military, I know that sometimes not taking care of the little details can even get you killed, in unusual circumstances. Like a clogged fuel filter in Death Valley, say. My 91 lifted SPFI Loyale has the filter before the pump, as did my 86 carbed GL wagon, and my 84 lifted carbed GL wagon. I just figure the Subaru engineers thought it was a good idea.

I'm 6'3" too and I've been in much bigger cars that have been much worse for front leg and headroom; headroom is good too, even with a sunroof. I don't stand much chance of fitting well in the back but I never sit there anyway. People seem to be quite critical of the carburettor on the Justy, is it really that bad? I've been thinking of buying a Mk1 Justy which of course only comes with a carb'.

Well Milford, the thing about the Hitachi carb used on the Justy is that there isn't much room for adjustment. You can adjust the idle & such but the mixture is computer controlled by a loop signal sent from the O2-sensor to the ECM. The ECM then sends a signal to a solenoid in the carb that constantly adjusts the AFR air-fuel-mixture There's another solenoid which controls extra richness on cold starts. Both of these solenoids go bad and from what I have heard they are basically obsolete. I was quoted $600 last month by my local Subaru dealership for a replacement carb. They also quoted me $505 for a new ECM but said it would take 2-3 weeks to get because it has to come from Japan. Dunno what the oxygen sensor (O2sensor) costs but I imagine it's around $70+ So, in a normal carbed car, you can rebuild your carburetor yourself for about $35 and tune it every so often. In a Justy, crap just wears out and can cost you more than a grand to replace. Most of us didn't pay a grand for the car in the first place. This is why the Puget Sound has so many Justys in the breaker's yards for me to dismantle!
Oh and Tom, you said your part, made your point and I made mine. I'm not sure what tools you carry with you in your Justy at all time but good smeggin' luck with your on-the-go filter change. I have driven my car from Seattle to mid-Oregon & back several times (600-800 miles round trip) stopping for fuel at any random station and never had a problem. Then again, I do this thing called preventative maintenance. Hope your Justy doesn't brake down in Death Valley or something.

Well,that confirms my suspicions.My carbed gen1 Justy does NOT have an ECM or whatever.Purely mechanical HITACHI carb,manual choke. What a strange bird landed in my backyard? Will post pics ASAP...

Yeah I would like to see pictures of that because I have never heard of a stock Justy that didn't have computer controlled carb. Hell, who knows whatthey did in East Europe! Have a look under the dash/steering wheel for a gold/silver box. Does your carburetor have any wires coming from it?
